JIT/AArch64: Support shifted immediate (#7165)

* JIT/AArch64: Support shifted immediate

As pointed out by MikePall in [1], shifted immediate value is supported.
See [2]. For example, `add x0, x1, #4096` would be encoded by DynASM
into `add x0, x1, #1, lsl #12` directly.

In this patch, a helper is added to check whether an immediate value is
in the two allowed ranges: (1) 0 to 4095, and (2) LSL #12 on all the
values from the first range.

Note that this helper works for add/adds/sub/subs/cmp/cmn instructions.

* Deprecatd CMP_IMM/ADD_SUB_IMM and add test cases

Macros CMP_IMM and ADD_SUB_IMM are deprecated and instead we use
this helper to guard the immediate encoding.

Add two 64-bit only test cases, since 64-bit integers are used
and tested inside.
